possessed various fields of view ani were suitabdly filtered to obtain qualitative spectral distribution information, All] channels vere recaded on Consolidates Recorders except the six back-scatter channels in the B-47 which were recorded on magnetic tape, The cameras were equipped with red and blue filters to obtain information at each end of the visible region of the spectrum, Several oameras vere equipped with apectroscopie attachments to obtain continucus spectra in the visible region, Two of these spectrographs were operated at the EG&G Parry photo tower, AIRCQIAFT POSITION It SPACE Information of the posifion in space of each aircraft is contained in Project 5.1 = B-47 Project 5.3 - B-66 Project 5,2 - B52 Project 5.4 = B57 Vie the post ahot reports of the following projecta: RESULTS Therral: The preliminary value of total thermal input to the aireraft obtained by Project 5.7 instrumentation 4a included in the post shot report of the appropriate project indicated above, Back-scatter Measurements on the B-47: The back-scatter inputs were unexpectedly low on the basis of predicted direot thermal inputs, and in consequence, resdable signals were obtained on only three of the six channels, The uncorrected values of these inputs is on the order of from 15 to 20 millicalories, Photopraphio Data: A total of thirty-five cameras were operated by Project 5,7 on this event, aircraft, Thirty-three of these were airborne tr four Of these, three failed to operate properly. It is impossible to state at this time how many of the remain'ng thirty films may subsequently prove to be unsuitable for analysis as the films have not been developed. It 48 believed that nearly all of these cameras obtained satisfactory recorde SNL - 26 - a ae
